Passive Fire Treatment

Fire Retardant Spray, Intumescent Coatings and Fire Retardant Paint Application

The risk of fire to buildings, property and equipment is a consideration necessary in all new buildings and structures so Passive Fire Protection is one of the most important factors to be considered. Passive Fire Protection is designing a building in such a way that it’s difficult for a fire to start and spread and therefore includes compartmentalization of the overall building through the use of fire-resistance rated walls and floors.

Walls with control joints are protected with a rated fire sealant. Structural beams and columns can be treated with varying systems including vermiculate based fire sprays, intumescent paint or fire rated board. Penetrations through fire rated walls are treated with fire pillows, fire rated mortars and collars.

Products specialised in but not limited to include the following:

Tremco Paints Nullifire

Nullifire is a next generation intumescent paint that is fast becoming the industry standard. Where other paints have traditionally had limitations such as cost, duration of application, weather resistance and durability Nullifire excels. Nullifires unique formula means it can be applied in significantly greater thicknesses than other comparable systems, but with standard airless plant. It can be sanded and re-coated within hours, can be sprayed onto un-primed steel, doesn’t require a topcoat, and can be left in the elements unaffected.

International Paints Charteck

Portolesi Structural is one of only a limited few certified installers of Chartek fireproofing in Australia, and is the only company to develop a completely unique method of application that creates a highly architectural bespoke finish to what’s traditionally been seen as a product for the high performance fields of gas, mining and marine. Chartek is a 2-part epoxy based intumescent system typically applied with a heated plural pump and requires a high degree of specialised training to become a qualified applicator. Not every project will require this level of product, but when the need arises Portolesi are the ‘go to’ company in Australia. Recently the largest intumescent project in Australia APHS Paramatta was completed by our skilled team of up to 20 employees with the architectural results nothing short of astonishing.

International Paints Interchar

International Paints have long been seen as the industry pace setters for protective and intumescent coatings. Their range of solvent and water-based intumescent paints covers all forms of application and in many cases can be applied on site.
